UNITED STATES JOHN JACKSON, OF COOPERSVILLE, MICHIGAN.

IMPROVEMENT IN CHURNS.

Specification forming part of Letters Patent No. 116,194, dated June2t), 1871.

To all whom it may concern:

Be it known that I, JOHN J AOKSON, of Coopersville, in the county ofOttawa and State of Michigan, have invented a new and useful Improvementin Rotary Churns; and I do declare that the following is a true andaccurate description thereof, reference being had to the accompanyingdrawing and to the letters of reference marked thereon and being a partof this specification, in which- Figure l is a perspective of my devicewith the cover removed and a portion of one side of the body broken outto show some of the parts. Fig. 2 is a detached view of one of thedasherrods with the dashers attached. Fig. 3 is a detached view of thecatch.

Like letters refer to like parts in each figure.

The nature of this invention relates to the construction of an improvedrotary churn, wherein a horizontal shaft is provided with three armsthrough said shaft, and with'dashers arranged in pairs upon each end ofsaid arms, so arranged that werethe paddles connected together theywould form an entire convolution of a screw, by means of which a muchgreater agitation of cream is had than can be obtained with dashers asordinarily construct-- ed. The invention consists in the peculiarconstruction and arrangement of the shaft, its arms, and the dashersconnected therewith, all as more fully hereinafter described.

In the accompanying drawing, A represents a churn-body with asemicircular bottom. B is a shaft journaled at one end into the side ofthe churn at a, and the shaft is the length of the interior width ofsaid churn. The opposite end of this shaft is provided with a recess, b,to receive the end of the shorter crank-shaft C, which is journaled intothe recessed support D, (which-is broken away in the drawing at thispoint,) and it is provided with a collar, 0, which, when the twosections of the shaft are connected, as above described, rests againstthe outside of the churn-body. The crank E, and any suitable power,gives motion to the shaft. F is a stop,-provided with a recess, d, uponits rear side; is pivoted to the churnbody, (as shown in Fig. 1,) andoperates under the recessed support D. It is designed, when the twosections of the crank are connected, that the recess d shall engage withthe collar 0 and hold the shaft in place.

When it is designed to remove the shaft for cleaning or other purposesthe stop should be disengaged from the collar, when the portion of theshaft connected with the crank may be withdrawn from the recess in theend of the shaft B, when the latter may be readily and eascured in pairsto each end of the rods H, as

shown in Fig. 2, a short distance apart, and at an angle of aboutthirty-five degrees with the shaft, so arranged that if they were allconnected they would form a perfect convolution of a screw around theshaft and at the ends of the rods. By this arrangement the cream is mostthoroughly agitated and broken up.

The cover J is shown detached and resting against one corner of thechurn.

The advantagesclaimed for a churn of this description are: First, itrequires but little power to rotate the shaft and its attachments. Thepaddles or dashers, being made oval on one side and flat on the other,enter the cream in the form of a wedge, thus requiring but little powerto force them through. Second, the paddles, being placed at an angle asdescribed, when they enter the cream force it to one side as well asupward, thus giving it a whirling motion into the air, thereby producingthe greatest commotion with the least number of revolutions. Third, therods, by being secured at difi'erent angles, as described, allow some ofthe paddles at all times to remain in the cream, thus giving a uniformmotion to the dash, when it is revolved, without the aid of abalance-wheel.

What I claim as my invention, and desire to secure by Letters Patent,is-

In churns, the shaft B, rods H, and paddles or dashers I, whenconstructed and arranged relatively to each other, substantially as andfor the purposes herein set forth.
